Hi and Welcome to the Pain Management Forum. I am sorry that you are unable to find a diagnosis and that you are experiencing increasing pain.
Have you had an MRI? What kind of physicians have you seen? Can you describe your pain a bit better? Does it originate in your shoulder?
Arm pain can actually be referred pain from other locations in your body. Do you have other symptoms? I'll look forward to your next post and more information.
Take Care, Tuck
Hello yoly and welcome to the Pain Forum.
I would suggest that you find an Orthopedic and see if they can find the problem. Have you had an MRI or CT Scan? If not, then I would definitely bring that up to the Doctor. You should see if you can get a referral from your Doctor to see an Orthopedic Doctor, they are much better with diagnosing pain when the limbs or back is involved. I'm sorry that I don't have further advise for you. Please take care and keep in touch,
My best,
Mollyrae
